This video from the CrazyRussianHacker YouTube channel shows you a clever use for a plastic fork. Roll up your chip bag, then take the pointy end of the fork and slide it over the bag’s last fold. Make sure the two outside prongs are one side of the chip bag and the inside prongs are on the other so it keeps the bag pinched shut. Next time you’re out having a picnic or barbecue, just save a few plastic forks so can use them to keep your chips from getting stale. You can even break off the handle of the fork and keep using them for as long as you like.
